用python3.6+tornado4.4实现的剧本杀助手工具（三）：【核心代码】

引用第三方库

import tornado.httpserver
import tornado.httpclient
import tornado.web
import tornado.websocket
import tornado.gen
import tornado.ioloop
import tornado.options
from tornado.escape import json_encode
import psycopg2
import pandas as pd
import time
import os
import hashlib
import logging
import pdb

设置kookie过期时长以及配置数据库连接参数

# ---config
cookie_time = 300000000  # cookie过期时延迟


# ---config
def conn_():
    conn = psycopg2.connect(
        database = "jubens",
        user="postgres",
        password="这个是密码，我不告诉你们",
        host="127.0.0.1",
        port="这个是端口，我也不告诉你们"
    )
    return conn

设置路由以及静态路径

# 设置路由以及静态路径
class Application(tornado.web.Application):
    def __init__(self):
        self.shoppingCart = ShoppingCart()

        handlers = [
            (r'/', IndexHandler)  ,  # 首页
            (r'/index', IndexHandler)  ,  # 首页
        ]

        settings = {
            "cookie_secret": "bZJa3sWbeLKod7GkHn/VB3bXwQt8c0R0kRvJ1/xJf9E=",
            "static_path": os.path.join(os.path.dirname(__file__), "static"),
            "templates_path": os.path.join(os.path.dirname(__file__), "templates"),
            "jubens_path": os.path.join(os.path.dirname(__file__), "jubens"),
        }
        tornado.web.Application.__init__(self, handlers, **settings)

渲染首页以及获取用户浏览器信息

# Index，就只有渲染首页的作用
class IndexHandler(tornado.web.RequestHandler):
    @tornado.web.asynchronous
    def get(self, *args, **kwargs):
        headers = self.request.headers  # 获取登陆浏览器头文件信息
        mobile = ["(Android;", "(iPhone;", "(SymbianOS;", "(iPad;", "(iPod;", "(Windows;", "(Linux;"]
        windows = ["(Windows"]
        yes = 0  # 1为浏览器，0为移动端,2为其他。
        self.render("templates/index.html")
    def post(self, *args, **kwargs):
        self.finish()

启动IO循环

if __name__ == "__main__":
    port = 8000
    print('webservers启动,http://127.0.0.1:' + str(port))
    tornado.options.parse_command_line()
    app = Application()
    server = tornado.httpserver.HTTPServer(app)
    server.listen(port)
    tornado.ioloop.IOLoop.instance().start()
